چکیده انگلیسی


• Porous graphite anode material is prepared by catalysis steam gasification.
• The pores facilitate lithium ion diffusion in graphite crystals.
• Pores in graphite buffer the anode volume change in charging-discharging cycles.
• The pores prolonged the cycling life time of the batteries.
• The pores improve the charging-discharging rate of batteries.

Porous graphite was successfully prepared by MoOx-catalyzed gasification. The prepared graphite with pores and channels exhibits an excellent cycling stability at high rate as anode materials for Lithium ion batteries. The porous graphite offers better cycling performance than the pristine graphite, retaining 84% of its initial reversible capacity after 1500 cycles at rate 5C. The effective synthesis strategy might open new avenues for the design of high-performance graphite materials.
